The cost of processing the feedstock into bioethanol; Such a calculation may or may not consider the following effects: The cost of the change in land use of the area where the fuel feedstock is grown. The cost of transportation of the bioethanol from the factory to its point of use; The efficiency of the bioethanol compared with standard gasoline
Biofuels include bioethanol, an alcohol made by fermentation—often used as a gasoline additive, and biodiesel, which is usually used as a diesel additive. Specific energy is energy per unit mass, which is used to describe the chemical energy content of a fuel, expressed in SI units as joule per kilogram (J/kg) or equivalent units. [1]
Food vs fuel is the debate regarding the risk of diverting farmland or crops for biofuels production in detriment of the food supply on a global scale. Essentially the debate refers to the possibility that by farmers increasing their production of these crops, often through government subsidy incentives, their time and land is shifted away from other types of non-biofuel crops driving up the ...
That being said, many believe that the potential pros far out-weigh the short-term cons. [1] [2] The process of growing the tree biomass is energy efficient compared with growing corn or sugar cane for ethanol. However, it also takes longer to grow trees than to grow corn, and so any accurate research on sustainability and crop rotation (even ...
A first-time CEO in her fifties, Shields was inspired to start her haircare business for women over 40 because of the way society talks about aging women. Instead of harping on the reasons you ...
The two most common types of biofuel are bioethanol and biodiesel. Brazil is the largest producer of bioethanol, while the EU is the largest producer of biodiesel. The energy content in the global production of bioethanol and biodiesel is 2.2 and 1.8 EJ per year, respectively. [17]
The study, which involved 106 peri- and postmenopausal women and was presented at the Endocrine Society’s annual meeting in May, indicates women should self-monitor their vasomotor symptoms and ...
The results were also more pronounced in women. “Findings highlight the potential role of diet quality in pain management and function, particularly in women,” the researchers concluded.
